I would like to download Firefox but am concerned about the warning I get that says this file type can potentially harm my computer. Don't know what to do!

hi georgiak, this might be a default warning message that windows shows you for every downloaded installer. in order to be be safe, only download firefox from the official location at https://www.mozilla.org/firefox/ and follow the steps from How to install Firefox on Windows in order to install it. thank you!
